ATTACHMENT FOR DOORS.

Application filed April 15, 1925. Serial No. 23,292.

To all whom it may. concern Be it known that I, VJILLIAM FIZZELL, Junior, a citizen of the United States, residing at Bradford, in the county of McKean and State of Pennsylvania, have invented an Attachment for Doors, of which the following is a complete specification.

My invention is an improvement in doors, and relates more especially to the construc-- tion of doors which are made of wood and are therefore lial' le to warp or shrink under atmospheric conditions. 7 i

The primary object of my invention to provide av wooden door with" a strip along one edge thereof, preferably the forward edge, in connection with means for adjusting said strip so that any warp or shrinkage of said door may be readily and conveniently compensated for and thereby provide that the door so constructed will lit closely withingj'th'e frame to exclude weather and present aneat appearance. V

. A'further object of my invention is to providea wooden door with an adjustable metal strip along one edge thereof which will not only maintain the proper width of the door with respect to the dooreframe in which it fits but will also reinforce the construction of this part of said door and provide a narrow overlapping edge to engage the doorframe and act as a Weatherstrip.

lVith these principal objects in view my invention consists in providing a box-like metal strip fitting over the forward edge of the door for slidable engagement therewith laterally andi means for adjusting said strip with respect to the door so as to compensatfor any warpage or shrinkage, the adjustable means in the present instance being in the form of bolts carried by said strip and threaded through lugs attached to the adjoining edge of the loor, with list springs interposed between the edge of the door and inner side of the face of the strip to main tain said strip in its normal position or adjustment; all as hereinafter fully described and particularly pointed out in the appended claims.

In the accompanying drawings Figure 1 is a front elevation illustrating the application of my invention.

Fig. 2 is a detail view of the door with the 'near side of the metal strip broken away; Fig. 3 is an enla g d detail View to illus:

trate the means for adjusting the metal strip laterally on the edge of the door.

Fig. l is a vertical sectional view on the line el l of Fig. 5.

Fig. 5 is a view of the edge of the door showing the metal plates which cooperate with the springs.

Fig. 6 is a plan view of the upper edge of the door, and V 7 is a transverse sectional view through the door and attached. strip, on the line 7 7 of Fig. 3.

My invention is applied to a wooden door of ordinary construction, and though 1 have illustrated in the drawings. a paneled door made up of side pieces 1.0, 10 and crosspieces 1.1, 11 at top and bottom onclosingthe panel work it will be understood that the adjustable metal strip hereinafter described may be applied to any other type of door that is liable to warp or shrink for the purpose of increasing the width of the same so that it may properly fit within the doorframe to which it is applied.

In carrying out my invention I provide a metal strip 15 which is box-like in cross-section to receive the forward edge of the door for slidable adjustment thereon laterally, said strip being the full. length of the door and having its inturned ends 16 extended rearwardly along the upper and lower edges of the door to reinforce this part of the construction thereof. The sides 17, 17, of the box-like metal strip closely embrace the forard end of the door, that is lit closely against the opposite sides of the vertical side piece 10, with the outer or connecting portion 18 of said metal strip disposed beyond the edge of the door; the strip thereby forming a side extension which will permit the. width of the door to be varied, while the reaiwrardly projectirne; end pieces tlQt'flll'Ptl to the side pieces 10 and cross-pieces ll of the door form plates to brave the construction thereof at these points. The end extensions 16 are secured to the upper and lower edges of the door respectively by means of screws 19 which pass through slots 16" therethrough so as to not interfere with the adj ustment. of the metal strip by the additional adjustment and securing means hereinafter described; in other words the slots permit adjustment without entirely removing the screws 19.

An accurate adj ust nentof the metal strip to vary the width of the door or take up shrinkage of the same is obtained by means of'bolts which are passed through the outer portion 18 of said strip and threaded into or through lugs 21 sunk into theouter edge of the door, said lugs being preferably formed integrally with plates '22 secured in place'of wood-screws 23, but of course may be in the form of ordinary nuts let into the edge of the door and held in place by said plates. For properly or more evenly adjusting the metal strip on the edge of the door three bolts and nuts are used, as indicated in Fig. .2 of the drawings. The head and shoulder of each adjusting bolt works loosely in the metal strip and by tightening the bolts said metal strip will be moved inwardly towards the adjoining edge of the door, and in order to hold the strip against the heads of the bolts a: flat metal spring 24 is employed in connection with each bolt, the body portion of the spring bearing against the inner side of the strip and its inwardly bent ends 24* bearing against the edge of the door or the wearplates 25 attached thereto. The belt 20 passes through an aperture 26 at thecenter of the flat spring, and in order that the bent ends 24 may project inwardly a suflicient distance the edge of the door is recessed, at

27, to receive the terminals of the spring, As the plate 22 is preferably extended at its ends over the recesses 27 these projecting ends are provided with slots-28 through understood, of course, that the accurate adjustment of the strip 15 itself provides a tight joint; in other words, this strip is capable of being adjusted so that the door will fit closely notwithstanding the width of the door proper may be decreased by shrinkage.

The utility of my invention will be readily appreciated and its operation easily understood, for in adjustin ithe strip with respect to the door-opening it is necessary only to loosen the screws 19 and then turn the bolts either to the right or left, according to the lateral movement of the strip desired, and then tighten said screws 19 to maintain the jointbetween the forward upright 10 and end cross-pieces of the door.

I- claim a 1. In combination with a door of wooden construction provided with spaced apart recesses in its outer edge, of-a metal strip U- shape in cross-section presenting side pieces embracing the sides of the door and a connecting portion beyond the adjoining edge thereof; together with a metal plate secured to the edge of'the door and having a lug with a threaded aperture seated in one of the aforesaid recesses and slots in the end-portions of the plate. in alinement with the other of said recesses. a flat metal bow-spring interposed between the metal strip and edge of the door with the inturned endsof said spring extending through the slots it the plate to bear on the bottom of the cooperating recesses, and abolt extending through themetal strip and spring and threaded in the apertured lug, whereby the metal strip is securely connected to theedge of the door and is adjustable laterally thereon to vary door and a longitudinal flange projecting outwardly on a line with one of the side pieces of the metal strip, the aforesaid connecting portion of the strip being bent at its ends and extended along the upper and lower edges of the door for attachment thereto; together with a plate secured to the outer edge of the door and having a lug with, a threaded aperture seated in one of the aforesaid recesses and slots in the end portions of said plate in alinement with the other recesses in the edge of the door, a'tlat metal bow-spring interposed between the metal strip and edge of the door with the inturned ends of said spring extending through the slots in the plate to bear on the bottom of the cooperating recesses, anda bolt extending through the metal strip and spring and threaded in the apertured lug.
